CARRIAGE-CURTAIN FASTENING.

SPECIFICATION forming part of Letters Patent No. 269,337, dated December19, 18$ 2.

Application filed October 28, 1882.

To all whom it may concern Be it known that I, ADOLPHUS G. SNELL, of NewHaven, in the county of New Haven and State of Connecticut, haveinvented a new Improvement in Carriage-Curtain Fastenings; and Idobereby declare the following, when taken in connection withaccompanying drawings and theletters ofreference marked thereon, to be afull, clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in-

Figure 1, a front "iew; Fig. 2, side view; Figs. 3 and 4, views showingthe disk in the two positions of the button Fig. 5, rear view of thebase with the disk removed Fig. 6, the disk detached Fig. 7, verticalcentral section.

This invention relates to an improvementin the device for securingcarriage-curtains, cominonlycalled carriage-button. Thesebuttons areattached to the posts or parts of the carriage, and the curtain providedwith an opening like a button-hole, to be passed on over the button andbe thereby secured. The heads of these buttons have been made so as tostand in line with the hole in the curtain, and so that the hole mightpass freely over the button, and then the button turned at right anglesto'the slit or hole, so as to prevent its accidental detachment. It isto this class of buttons that my invention particularly relates, theobject being to improve the devices whereby the button is locked eitherin the position to receive the hole in the curtain or turned into atransverse position to secure the curtain. Suchlocking devices have beenemployed in connection with such buttons; but usually there has-beenmore or less play required for the shank of the button in its bearing.This play causes a wear of the parts. which soon renders them almostuseless; and my invention, whereby these difficulties are overcome,consists in the construction of the button as hereinafter described, andmore particularly recited in the claims.

A represents the base or plate, which is secured to the post orstationary part of the carriage, and at points corresponding to thebutton-holes through the curtain. On its outside center is a raisedprojection, forming a body, B, onto which the button-hole of the curtainwill pass, and is in extent at least equal to the thickness of thecurtain at the button hole.

It is oval in shape, and centrally through itis- (No model.)

a hole forming a seat for the shank a of the button C. The button Ccorresponds in shape to the body B, and is arranged so as to turn uponits shank a in a plane parallel with the base A, say, from the positionseen in Fig. 1 to the position seen in broken lines, same figure-thatis,its normal position is shown in full lines,and turned into itstransverse position in broken lines, and when so transversely turned itsends project beyond the sides of the body B, as indicated in Fig. 1. Theback or rear side of the base A is recessed, as at b, (see Figs. 5 and7,) to receive a disk, (I, as seen in Figs. 3, 4, and 7, the disk showndetached in Fig. 6. This disk is recessed at its center, as at e, andhas a central hole, through which the end of the shank a extends, and isriveted down upon the disk, as seen atf, Fig. 7, and so that the collarthen serves as the means for retaining the button in its place-that is,prevent its movement in the direction of the axis of its shank, but yetpermitit to turn freely upon its shank as a center. The riveting of theshank upon the disk is made to secure the two parts together, so thatthe disk will turn with the button. This may be done by making the holethrough the disk of irregular shape, as seen in Fig. 6, and the shank ofcorresponding shape, or otherwise, it only being essential to theinvention that the disk shall revolve with the button.

On one side of the disk a tongue, h, is out concentric with the centerof the disk, the out being of sufticient length to give considerableelasticity to the tongue. At the end of the tongue an indentation fromthe outside, as at 2', forms a corresponding projection on the oppositeside, as seen in Fig. 7.

In the cavity on the back of the base in which the disk rests areseveral depressions, m m and n n, (see Fig. 5,) each of whichcorrespondsto and standsin the path of the inward projection, t, on thetongue 11. The depressions m and a and the projection i are conical inshape, so that while the projection on the tongue will fall into thosedepressions a little power applied to the button to turn it will forcethe projection ifrom the depression with which it may be engaged, thespring of the tongue yielding for that purpose. The indentations aremade-say those at n-in the vertical line of the button when standing inthe position seen in Fig. 1, and so that when the button is in thatcondition it will be held by the projection 43 standing in one of thesedepressions n, and as seen in Fig. 3, but when turned at right anglesthereto the projection twill fall into one of the depressions m, as seenin Fig. 4, and thus will secure the button in either of the twopositions. The two depressions a n, being opposite each other,willsecure the button if it be turned either end up, and so that thedepressions m m will secure the button whichever way it may be turnedinto its transverse position. A single depression at and a singledepression m will serve the purpose of securing the button, providedalways that the button be turned to either one of those two positions.

By this construction the button has no a xial movement in order toenable it to be locked in either its fastening or unfastening position,but is firm in its seat.

The disk may be sufliciently elastic without the cutting of the tonguetherefrom; but I prefer to cut the tongue, as it gives a better spring,and one less liable to set.

Instead of making the projection on the tongue, it may be made on thebody, and the depression in the tongue; yet I prefer the firstconstruction. 1

I claim- 1. The base A, constructed with the body B, to receive thecurtain, combined with the button G, having its shank a through thebody, i

with a disk secured to the shank upon the reverse side, so as to turnwith the button, the disk and body provided with correspondingindentations and projections, whereby the button will be held in eitherof its two positions, substantially as described.

2. The base A, constructed with the body B, the button O, having itsshank to extending through said body, and so as to be turned in a planeparallel with the base, the base constructed with a recess on its rearsurface, and a disk in said recess secured to the shank of the button,and so as to rotate in said recess with the button, the body and diskconstructed with corresponding projections and depressions, whereby thebutton is locked in either of its two positions, substantially asdescribed.

3. The base A, constructed with the body B, combined with the. button G,having its shank through the body, and so that the button will turn inaplane parallel with the base,and adisk on the rear surface of the platesecured to the shank of the button, and so as to revolve with thebutton, the said disk constructed with atongue, 1:, the said tongue andthe surface of the plate over which it moves provided with correspondingprojections and depressions, whereby the button is secured in either ofits two positions, substantially as described.
